cles; and the objects and nature of the in-' ventifin will be readilyunderstood by those skilled in the art in the light of the followingexplanation of the structures shown in the accompanying drawings asexamples for pur-- poses of descri tion from among other see structionsan arrangements within the spirit and scope of our invention. v

An object of the invention is to rovide certain improvements in automobie 6011-.

struetion and arrangement for the purpose of avoiding the employm t f cf and transmission-gearing and of'providing a simple and economicaldirect drive between the motor and axle. or driving wheel or wheels.

A further obj ects of the invention isto rovicle certain improvements inantozno ile construction whereby a direct drive is provided between theengine-motor shaft and wherein the engine-shaft is movable forrevex-sing, driving, and disconnecting the driv-' mg connection with thedriven axle or wheels of the vehicle. I 1 A further object of theinvention is the pro duetion of certain im rovements in arran emeritsand combinations of parts, where y an efficient, simple, and economicalauto mobile construction will be produced. The invention consists incertain novelfeatnres in construction and arrangement, or incombinations of parts and elements, as more Referring to theaccompanying drawings, Figure l'fis atop plan view partiallyillnetrating-the running-gear and motor carried thereby.

frictional engagement with the vehicle drivewheels mind with the 'driv'g-beits operatively disconnecting the eilgineshait and vehicledrive-wheels. Fig. 4 is a oross-sec tion on the line 44, Fig. 1. Fig: 5is a crosssectional view on the line 5 5, Fig. 2. Fig. 6 is a top planview of a runningsgear and a motor carried thereby and slidable to itsvarious positions for forward drive, non-drive, and reverse drive. Fig.7 is a cross-sectional view on the line 7 7, Fig. 6.

in the drawings we show somewhat diagrammatically the rumiing-gear orchassis of a motordriven vehicle to show so much of the frame as may benecessarytosup ort the motor and driving or transmission etween driveposition with the friction-wheels in the same and the assessin wheels.

' For instance, theriinning-gear frame shown comprises the; longitudinalor side bars 1, cross-bars 2, and intermediate or motor-supportinglongitudinal beams 3. These bars are ri idly secured together to form astrong rigid emework.

4 indicates the front wheels, which can be mounted and connected withthe framerin any suitable manner and by any desirable means. 7 r

5' indicates the rear or drive wheels of the frame. in an desirable orwell-known manvehicle, which can be mounted on anyjsnit l able axle orotherwise connected wzth the not. At its inner side we showeach drive- Iwheel 5 provided with a concentric usually grooved friction wheel orcured thereto. The drive-wheel5 can be provided withany suitable tires'7, such as 8' indicates any suitable motor or engine,

pulley; 6, rigidly sepnenmatic, cushion, solid-rubber, or other 7 and 9is the horizontal transverse engine or drive shaft. We usually emplo .avertically arranged explosive engine-2h J gasoleneengine and the pistonthereof (not shown) the engine-shaft, which in the specific" ex- "em leee show hg r instance,

" is connected in any suitable mannerto rotate IIO faces, such as 7, .ofthe drive-w eels.

engine is arranged between and is carried by the frame-beams 3, .and theengine-shaft 9 extends through the crank-box i0 and boxes 11 andprojects in opposite directions therefrom beneath the frame-bars andbeyond the opposite side bars to points in advance of or opposite thetwo drive-wheels 5. The op 0- site ends of the engine-shaft are providbdwith small annular friction drive-surfaces, usually in the form ofrooved pulle s 12, arranged in the vertica planes'of t e drivewheels5'and opposite and normally out of operative relation to annular orcontinuous friction drive-surfaces of said wheels, res ectively. Forinstance, in the examples i'lustrated the friction drive-surfaces 12 ofthe engine-shaft are shown opposite and adapted to be moved to frictiondrive engagement with the tires 7 of the ground or drive wheels 7. Theopposite end ortions of the engineshaft are also provided with usuallygrooved belt or band pulleys or inions 13, respectively, o posite theband or belt pulleys 6, rigid wit the drive-wheels and having drivingconnection therewith through the medium of the endless flexible frictiondrive belts or hands 14.

The engine-shaft is so carried and mounted as to be movable to variouspositions at varying distancesfrom the drive-wheels 5 for the purpose ofactuating the drive-wheels to move the vehicle forward or to throw outor break the driving connection or relation between the engine-shait andsaid drive-wheels or to reverse the drivin relation between said shaftand wheels for 51s purpose of backing the vehicle. For instance, whenthe enine-shaft is in forward-drive position it is at its advancedposition, thereby tightening the belts 14 tooperative driving relationwith the friction reverse-drive surfaces. 12 advanced from and out ofoperative driving relation with the correspondin friction-sur- When theengine is operating and the en inc-shaft is in said forward-driveposition, t e vehicle will be propelled forward through the medium ofthe friction-belts 14. To disconnect the driving connection or relationbetween the engine and drive-wheels, permitting the engine tocontinueits operation without prope ing the vehicle, the engine-shaft is movedto its intermediate or non-drive plosition, wherein the belts areloosened 0r eng so slack as not to have driving relation with thedrive-wheels5 and wherein the reverse-drive frictionsurfaces 12 and 7are out, of a contact or relation. engine-shaft is moved to its rearwardor reverse-drive position, wherein the'slackness of the belts 14prevents their driving relation with the wheels 5 and wherein thefiriction reverse-drive surfaces 12 are" in direct frictiondrive-contact with and relation to the surfaces 7 of the drive-wheels.

To back the vehicle, the

cylinder and mounted to oscillate in the elevated journal-boxes 16,secured on the framebeams 3. The engine swin s on these truntions, ashereinbefore described. Additional supports for the engine-shaft endportions can be rovidedL- Forinstance, 17 represents depen ing swinginghangers, in the lower ends of which the engine-shaft turns. Thesehangers at their upper ends are hung to swing from theupwardly-extendingbrackets 18, secured on the frame side bars 1 and soarranged that the axis on which each hanger 17 .swings will be in theaxial line of trunnions 15 on which the engine swings.

In the construction shown by Fi 6 the engine-cylinder is provided withrigiilate'rallyprojectin supporting-brackets 19, resting on and slidable longitudinally of the beams 3 and lapping under said beams to holdthe engine to the same. The end portions of the engine-shaft rotate inhangers 20, depending from and supported and slidable on the frame sidebars 1, usually about as shown, the two constructions shown beingpractically the same except for the differences between the pivotal andslidable mountings for the engine and'shaft. As a means which can beconveniently employed for shifting the engine-shaft to its variouspositions we show a transverse rock-shaft 21, arranged in advance of theengine-shaft and mounted to rock in hangers 22, de ending from theframebars. This rock-sha t is provided with depending rocker-arms 23rigid therewith, and these arms are pivotally connected by the rearward]-extending push and pull links 24 with the ower portions of the enine-crank box and with the lower ortions o the hang ers 17 of Fig. 1or'the angers 20 of Fig. 6. It will hence be observed that the engineand IIO engine-shaft will be moved forwardly or rearwardly by theoscillation of said rock-shaft through the medium of said arms andlinks. 25 is an upwardly-projecting manually-operated lever, such as ahand or foot lever, r1 'd with the rock-shatt 21 and provided withmanually-controlled locking and releasin means such as a fixed toothedsector 26 an a: he -clip and pawl 27, for locki the lever 25,. and hencethe e e-shaft, m t e desired adinstment. It is o vious that according top the .particuiar arra'ngment shown rearward movement of the lever 25will adjust. this engins-shaft to forward-drive (position, while artialforward throw of sai lever will adust said shaft to'non-drive position,while complete forward throw of said lever will ad just said shaft toreverse-drive position. The
